Review: Will never use digital thermometers again - I have two of these and four digital thermometers. I decided to test them against one another. The digital thermometers were all over the map with readings, but these two always matched. I set a timer for 10 mins for these. The digitals beeped anywhere from about 6 seconds to 1 minute depending on the brand and varied as much as 1 degree from each other. More convenient perhaps, but not worth sacrificing accuracy.
Review: DOESN'T WORK ! - Many years ago I bought a GeraThermometer. This thermometer worked fine. Recently I bought a 2nd thermometer for my first aid kit. This one, which looks exactly like my 1st one, does not work at all. The indication line stayed at 102 degrees. I could not shake the indicator line down. I put it in the freezer and it remained at 102 degrees. The Gera Thermometer is not returnable. Don't buy the Gera Thermometer !

## Questions & Answers

**Q: How do get temperature down to start.**
A: Hi Betty! I sure hope you are doing well🙌🏼🙌🏼 So what you dobis hold the thermometer at the end, not the end you put un your mouth, and shake it really hard downwards. Make sure you have a good grip cause youll end up tossing it otherwise or you can sinply run it under cold water. I hope this helps Betty! God bless you and I hope all is well.

**Q: How do i get it to work how do I get it to go past 98.**
A: If you do not have a temp it will not get higher in temperature. So thats a good sign. Otherwise it might be broken.
